Accucraft Forney fuel regulation

The fuel valve is so touchy on my Forney. Is there a mod or repair I can make to increase the effective range of the valve. I only have about 2 - 5 degrees to adjust the flame level to get a nice speed below “Lionel speed”.

I think they are all touchy. Your problem might be as the fuel tank warms the flame gets hotter. Then you have to lower the flame as this occures. My does the same. If speed is your problem then lower the throttle but dont forget its like the Ruby. It will run fast especially if you have grades. Hook RC to it, it will make a hudge difference. A hot flame should not make it go faster, it will just cause the saftey valve to go off and wast water.

Contact Jay from the Train Department I believe there is something that can be added or replaced. I forget.

Thanks Shawn. I have R/C on the Forney, but only on the throttle and Johnson Bar, not on the fuel. I try to regulate the fuel by the sound of the burner and try to keep the steam coming off the pressure valve to a minimum or none to extend the run time and not run out of water before the fuel.
I’ll check with Accucraft. Thanks!

Hi David, Yes there is a fix and it is a new gas spindle for the gas tank. It allows you to have double the adjustment with 2 times the thread pitch. Another option is a new gas jet that I offer. Its is higher quality and typically makes a big difference. I am also getting in some other jet sizes so you can tune you burners higher and lower with no3 no 5 or no7 jets. The no3 and no5 would be suitable for the smaller locos and the no7 more geared toward large boiler locos like the Ks or bigger standard gauge

Excellent Jason. That sounds like exactly what I need. What do you suggest and do I need a special tool?

PM sent.

No Special tools just standard small wrenches and allen keys that you would normally have for working on these locos. The gas valve there has a bushing that is threaded into the gas tank after you remove the old needle, that needs some liquid pipe sealant on the outer threads only before its installed. I usually have small tubes of it available for about 6-7.00. The sealant I also use for any other boiler fittings that have threads.
